好吧，我正在尝试制作一个应用程序，允许教师给予或从学生那里获得积分。我花了好几个小时试图让它发挥作用，现在我正在放弃。每次按下+1或-1按钮时我都需要更改标签，但标签不会让步。这是我达到的最远（实际代码接近底部）：

答案 0 :(得分：0)
有几个问题。
第一个问题，正如评论中指出的那样，您需要将callable传递给.connect()。在您的示例中，您实际上是在连接操作期间调用adder()函数。
第二个问题是，您点击按钮时每次添加信号连接。您只需要建立一次连接，通常在您的小部件__init__中。
以下是解决此问题的方法。
plus_point() label_set
plus_point()函数调用home（我假设它只调用一次？），或者在__init__方法中调用{。}}。plus_point中建立您的联系
self.plus_one1.clicked.connect(lambda: self.adder(1))
